wop

美国俚语，通常认为来自意大利方言guappo,无赖，恶棍，傻瓜，含贬义。俗词源认为来自without passport的缩写词，因20世纪初大量没护照的意大利人涌入美国。

wop (n.)

derogatory for "Italian," 1912, American English slang, apparently from southern Italian dialect guappo "dandy, dude, stud," a greeting among male Neapolitans, said to be from Spanish guapo "bold, dandy," which is from Latin vappa "sour wine," also "worthless fellow;" related to vapidus (see vapid). It is probably not an acronym, and the usual story that it is one seems to date only to c. 1985.
